Ok, I finally got a chance to change the oil on the 4.8 and take some pictures. I'll post a full writeup in a few days, but in the meantime I'll post a picture of what you need to get to under the engine. On my X5, there were no covers. In the picture, the drain plug is closer to the front of the truck and the oil filter canister is farther back. In the picture you can see the round silver drain plug at the bottom of the oil filter canister. After draining the oil, you need to remove that drain plug before unscrewing the canister cap. The drain uses a hex socket or key and the canister itself uses a large socket. The filter kit has a crush washer for the oil pan drain and rubber gaskets for the oil canister plug and cap.
